[0023] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined unless they conflict. For ease of description, the words "upper," "lower," "left," and "right" appear below merely to indicate the directions of upper, lower, left, and right in the accompanying drawings and do not limit the structure.

[0024] Example 1

[0025] like Figure 2 As shown, a battery cell cleaning device provided in this embodiment includes a first fixed plate 1, a movable plate 2, a support seat 3, a driving mechanism 4, a first chuck 5 and a second chuck 6.

[0026] The movable plate 2 extends in the X direction, the first fixed plate 1 is placed at the upper end of the middle part of the movable plate 2, the two ends of the movable plate 2 extend to the outer ends of the first fixed plate 1, and mounting platforms (unnumbered) are provided on the upper surfaces of the two outer ends, and the mounting platforms are used to install the driving mechanism 4.

[0027] In this embodiment, the movable plate 2 is a non-movable structure, and is fixed integrally with the first fixed plate 1 by being overlapped with it from top to bottom, and both are installed on the workbench of the cleaning station at the same time.

[0028] Two support bases 3 are spaced apart along the X-direction on the first fixed plate 1 (the number depends on the length of the battery cell 12; only one support base may be provided). The support base 3 includes a first lifting mechanism 31, a clamp 32, and a mounting end 33. The first lifting mechanism 31 is a cylinder, the cylinder barrel (fixed end) of which is fixed to the first fixed plate 1, and the power output end (telescopic rod) of the cylinder is connected to the clamp 32. The clamp 32 is a plate-like structure, with a concave arc at its upper end that matches the cylindrical surface of the battery cell 12 to form the mounting end 33.

[0029] The first lifting mechanism 31 is controlled by a solenoid valve 9 for vertical movement. The pressure regulating valve 10 controls the first lifting mechanism 31 to maintain stable air pressure and adjust the pressure during the lifting process. The first lifting mechanism 31 is used to lift the battery cell 12 to the working position or lower it to disengage the battery cell 12.

[0030] The drive mechanism 4 includes a first mounting plate 41, a second mounting plate 42, a first drive source 43, a second drive source 44, and a guide rail 45. The first mounting plate 41 is connected to the mounting platform of the movable plate 2 on a side away from the first fixed plate 1. The guide rail 45 is placed on the movable plate 2 and is located beside the first mounting plate 41. The guide rail 45 extends along the X-axis. The second mounting plate 42 is connected to the guide rail 45.

[0031] The first driving source 43 is a screw motor, a cylinder of which is mounted on the first mounting plate 41 , and a power output end (screw) of the first driving source 43 is connected to the second mounting plate 42 .

[0032] The second drive source 44 is a servo motor. One of the second mounting plates 42 on either side of the support base 3 in the X direction is used to mount the cylinder of the second drive source 44, while the other second mounting plate 42 is rotatably mounted on the first chuck 5. The power output end (motor shaft) of the second drive source 44 is connected to the second chuck 6 via a coupling (unnumbered). The first drive source 43 outputs linear degrees of freedom, while the second drive source 44 outputs rotational degrees of freedom. The first chuck 5 is equipped with an encoder 18, which is mounted on the second mounting plate 42.

[0033] The first driving source 43 is used to drive the second mounting plate 42 to move along the guide rail 45 on the X-axis, thereby driving the two second mounting plates 42 and the first clamps 5 and the second clamps 6 thereon to move closer to or away from each other to clamp the two ends of the battery cell 12 or release the battery cell 12.

[0034] The end side of the first clamp 5 is provided with an annular groove for matching with the explosion-proof valve surface of the battery core 12 , and the end side of the second clamp 6 is provided with a concave column hole for matching with the pole surface of the battery core 12 .

[0035] The second chuck 6, which is equipped with the second drive source 44, is the active one, and the first chuck 5 is the passive one. As the active second drive source 44 drives the second chuck 6 to rotate, the passive encoder 18 synchronously reads the pulse signal to determine whether the battery cell 12 is slipping during rotation, thereby adjusting the rotation cleaning speed according to the actual processing conditions.

[0036] The solenoid valve 9 and the pressure regulating valve 10 are mounted on the movable plate 2 via a support plate 17 .

[0037] Example 2

[0038] The first embodiment is repeated, except that the battery cell cleaning device provided in this embodiment further includes a proximity switch 11, a second lifting mechanism 7, and a second fixed plate 8 positioned below the movable plate 2. In this embodiment, the movable plate 2 is connected to and raised below the first fixed plate 1. The second lifting mechanism 7 is used to drive the movable plate 2 to rise and fall between the first fixed plate 1 and the second fixed plate 8.

[0039] The second lifting mechanism 7 includes a third driving source 71, a screw rod 72 and a guide column 73. The third driving source 71 is a servo motor, and its cylinder body (fixed end) is installed on the second fixed plate 8. The second fixed plate 8 can be fixed under the workbench of the cleaning station, and the first fixed plate 1 can be fixed on the action table of the cleaning station. The power output end (motor shaft) of the third driving source 71 is connected to one end of the screw rod 72 through a coupling, and the other end of the screw rod 72 is connected to the first fixed plate 1. The screw rod 72 is threadedly connected to the middle part of the movable plate 2. The guide column 73 is connected between the first fixed plate 1 and the second fixed plate 8, and the movable plate 2 is passed through the guide column 73. The guide columns 73 are arranged around the first fixed plate 1 and the second fixed plate 8.

[0040] The third driving source 71 is activated to drive the screw 72 to rotate. Under the action of the guide post 73, this rotation is converted into the lifting movement of the movable plate 2 on the Z axis, thereby driving the first chuck 5 and the second chuck 6 to move up and down. The proximity switch 11 is used to sense the upper limit position of the lifting of the movable plate 2. The proximity switch 11 is fixed to the work station and is located next to the battery cell cleaning device.

[0041] The method for using the battery cell cleaning device provided in this embodiment is as follows:

[0042] The first and second chucks 5, 6 are in their initial positions, spaced apart from each other. Support base 3 is also in its initial position. A dedicated manipulator places the battery cell 12 onto the mounting end 33 of support base 3 (aligning the cell 12's head and tail with the chucks). The manipulator then withdraws. Solenoid valve 9 activates the two first lifting mechanisms 31, extending the cylinder rods and moving the clamp 32 and the cell 12 mounted thereon upward along the Z axis to the cleaning position.

[0043] The second lifting mechanism 7 is activated to drive the movable plate 2 and the driving mechanism 4 and the first and second clamps 5 and 6 thereon to rise until the proximity switch 11 senses a signal. At this time, the axis of the clamp is aligned with the axis of the battery cell 12.

[0044] Then, the first drive sources 43 of the two drive mechanisms 4 are activated, causing the first chuck 5 and the second chuck 6 to move synchronously toward the battery cell 12. The first chuck 5 clamps the explosion-proof valve surface of the battery cell 12, while the second chuck 6 clamps the pole surface of the battery cell 12. The clamping pressure is sensed by the pressure sensors provided on the chucks to confirm that the battery cell 12 is released and locked.

[0045] The solenoid valve 9 is again used to synchronously lower the two first lifting mechanisms 31 to the standby position (initial position), allowing the mounting end 33 to detach from the battery cell 12. The second drive source 44 is activated to drive the second chuck 6 to rotate, while the first chuck 5 is driven. The encoder 18 synchronously reads the pulse signal to confirm whether the battery cell 12 slips during rotation, thereby adjusting the cleaning speed according to the actual processing situation.

[0046] After cleaning is complete, the dedicated manipulator is used again to remove the battery cell 12 from the assembly line, and the first and second clamps 5 and 6 are withdrawn to their initial positions by the drive mechanism 4. This completes the cleaning of one battery cell 12. The above steps are then repeated to clean the remaining battery cells 12.

[0047] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
